Hmmm...must be time for an update, this thread was now on page 2 of my own posts.
(thanks for the bump Matt)
It's coming up for two months since I have done any work on this project, mostly due to busy work/family/holiday life, but all is good.
The Grinhill 2 has been working reliably as daily transport (dry weather only), and I have decided to leave it as is for now. This means I must find another bike to build.
In order to set up the geometry, I decided to do a prototype in steel before moving on to aluminium.
Before Christmas, I dragged out the stick welder (inspired by Aussiejester
). Unfortunately my automatic helmet had stopped working, so this was done one-handed with a hand-held mask (yes I know thats a lame excuse for some very ugly welds!)
On the electrics side, I have some new LiPo but haven't built the packs yet. Hopefully the new GGoodrum boards will be available soon, he seems to have sold out of the old ones. I have also ordered a Meanwell 350W Power supply to do the charging.
